DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] As attached Figures 1 to 3 The toy mechanical finger shown includes a middle finger sleeve 1, a proximal finger sleeve 2 and an additional finger 3. The middle finger sleeve 1 and the proximal finger sleeve 2 are worn on the middle finger and proximal finger of the user's finger respectively, and the additional finger 3 is also connected between the middle finger sleeve 1 and the proximal finger sleeve 2.

[0029] Among them: the user passes the finger through the proximal finger sleeve 2 and the middle finger sleeve 1 respectively, and bends the middle knuckle of the finger, so that the middle finger sleeve 1 drives the additional finger 3 to deform as the middle knuckle bends, so that the additional finger 3 is displaced compared to the proximal knuckle. An additional finger 3 can be added on the basis of the existing finger structure, and the extension and contraction state of the additional finger 3 can be controlled as the middle knuckle of the finger is bent or straightened.

[0030] Example 2

[0031] Based on Example 1, the solution in Example 1 is further detailed in combination with the following specific working methods. Figures 1 to 10 As shown, see the following description for details:

[0032] As a preferred embodiment, the end of the additional finger 3 is connected to the additional finger connecting rod 1 31 and the additional finger connecting rod 2 32, which are distributed in front and back order, by means of a mounting axis, and the additional finger connecting rod 1 31 is symmetrically arranged in two groups; further, as the additional finger 3 undergoes relative displacement compared to the proximal finger joint, the additional finger connecting rod 1 31 and the additional finger connecting rod 2 32 rotate compared to the middle finger sleeve 1 and the proximal finger sleeve 2.

[0033] As a preferred embodiment, the two sets of additional finger connecting rods 1 31 are provided with a middle finger sleeve connecting shaft 311 and a proximal finger sleeve connecting shaft 312 at one end away from the additional finger 3, and the middle finger sleeve connecting rod 11 is installed on the side of the middle finger sleeve 1 facing the additional finger 3 using a rotating shaft, and a middle finger sleeve connecting hole 111 is opened on the rod body of the middle finger sleeve connecting rod 11, and the middle finger sleeve connecting shaft 311 passes through the middle finger sleeve connecting hole 111, and the additional finger connecting rod 2 32 is connected to the proximal finger sleeve 2 by the additional finger connecting shaft 321, and the two sets of additional finger connecting rods 1 31 are connected to the proximal finger sleeve 2 by the middle finger sleeve connecting shaft 311; further, the middle finger sleeve connecting shaft 311 is used to connect the middle finger sleeve The structural feature that the finger sleeve connecting rods 11 can rotate relative to each other allows the bent middle finger sleeve 1 to drive the middle finger sleeve connecting shaft 311 to move forward, thereby driving the additional finger 3 to tilt forward. At this time, since the proximal finger sleeve connecting shaft 312 is also rotationally connected to the proximal finger sleeve 2, the displaced additional finger 3 is lifted upward while tilting forward. Finally, it should be noted that the additional finger connecting rod 2 32 and the proximal finger sleeve 2 are connected by the middle finger sleeve connecting shaft 311, so when the additional finger 3 tilts forward and lifts, its displacement distance is limited by the additional finger connecting rod 2 32, and it can assist in pulling the additional finger 3 back to its original position when the middle finger joint returns to its straight state.

[0034] As a preferred embodiment, the mounting shaft between the additional finger 3 and the additional finger connecting rod 2 32 is inserted into the additional finger connecting hole 33; further, the rotatable characteristics between the additional finger connecting hole 33 and the mounting shaft ensure the smoothness of the relative displacement between the additional finger 3 and the additional finger connecting rod 2 32.

[0035] The working process of the present invention is as follows: first, the user passes the finger through the proximal finger sleeve 2 and the middle finger sleeve 1 respectively, bends the middle knuckle of the finger, and the additional finger connecting rod 1 31 and the additional finger connecting rod 2 32 rotate compared with the middle finger sleeve 1 and the proximal finger sleeve 2. The bent middle finger sleeve 1 drives the middle finger sleeve connecting shaft 311 to move forward, thereby driving the additional finger 3 to lean forward, and at the same time, the displaced additional finger 3 is lifted upward while leaning forward, and the additional finger connecting rod 1 31 and the additional finger connecting rod 2 32 can assist in pulling the additional finger 3 back to its original position when the middle knuckle returns to a straight state. The above is the working principle of this toy mechanical finger.
